If a typical Adélie penguin ingests 240 milligrams of fluorine every day from the krill that it eats, how many kilograms of krill must it be eating each day?

Answer:

0.08 kg

Explanation:

Krill scavenge fluorine from seawater (which contains about one milligram of fluorine per kilogram) and concentrate it in their chitin shells, where levels exceed 3,000 milligrams per kilogram. We can use this conversion rate to calculate the mass of krill.

240 mg = (3000 mg/kg) m

m = 0.08 kg
